自适应滤波器和维纳滤波器一样是符合某种准则的最佳滤波器。维纳滤波器参数固定，适用于平稳随机信号的最佳滤波，设计时需要知道 和 这些先验知识，应用困难。-Like adaptive filter and Wiener filter is the best filter to meet certain criteria. Wiener filter parameters fixed, applicable to stationary random signal filtering, need to know these prior knowledge, application design difficult.
